A well known hunter-warrior who killed Yugo's brother after his wife Nana betrayed him over her fears of his building a successful flying machine. As a veteran hunter-warrior, he had no qualms about helping Nana betray her husband and had no remorse in going after Hugo when he in turn became a bounty. He was a firm believer in the hunter-warrior code, seeing Alita's relationship with Yugo as a betrayal of it.
